Only test email is work

Hello,

I am using Postman smtp plugin to handle all mail delivery from my site. But it seems Newsletter plugin only work partially with Postman smtp.

All mail from Newsletter plugin not delivered, including welcome and subscription confirmation email… But when i test using Newsletter diagnostic and send test email, it works.. It makes me confused, why test email works and sent instantly but other mail from your plugin is not delivered..

CMIIW but from what i know, Postman smtp change all wp_mail delivery to use smtp (in my case im using gmail). So all wp_mail function in my site handled by postman smtp. So if someone register in my site, confirmation mail is send instantly and handled by Postman. That is why when im testing email from Newsletter diagnostic menu, email send instantly..

I tried every configuration on newsletter but the only email sent was from diagnostic testing mail..

Any help will be apreciated. ??
